CUSHIONED WHEEL.

Application filed August 31, 1920. Serial No. 407,257.

To (a l wimm it l'i"i'('6-:1/ concmw:

Be it known that l, JOSEPH H. HUBBLE, citizen of the United States, residing;- at 'lehoa, in the county of ,Vhitman and State of Washington have invented certain new and useful Improvements in Cushioned lheels, o1 which the "following is a specihcation.

llhis invention relates to improvements in vehicle wheels and more particularly to that type prm'ided with pneumatic cushioning means the eneral object being: to gvri'avide a wheel which, althougl'i it will employ solid tires, will possess substantially the same resiliency as a wheel equipped with pneumatic tires,

One ob' ect oi? the invention is to so conpr. innatic cushioning devices for that these devices will be actuated automatically to take in the required volume i air to produce the desired cushioning efand will act effectually to absorb all he and impacts incident to travel '01 the vheel over rough road surfaces.

Another object of the invention is to prowhecl of the class mentioned which in ci'nistruction and YiilG a is simple and durable equally as subs itial spokes. I

:onn ianying (Ira-wings: i is a view partly in side elevation and partly i" ical section illustrating a i in accordance with the invenion t Figure 2 is a vi w similar to Figure 1 looking at the opposite side of the wheel, a portion oi the brake drum being broken awav Figure 3 is a vertical diametric sectional view throup h the wheel. k

Figure is a perspective new 01' a fragrnent of the rim and annular rim-securing member.

'lhe wheel embodying the invention comprises a hub 3% which is peripherally chan nelen so as to provide spaced flanges and which adapted to be fitted for example upon the spindle of the axle shaft 1 and secured in place by means of a nut 2. Bolts 5 are secured through the flanges or the hub 23 and extend across the channeled periphery of the hub and constitute wrist pins upon which are fitted sleeves 6 formed at the inner ends of piston rods which constitute parts of the spokes of the wheel, the

of the invention as a wheel haviiu;

sleeves 6 having bearin upon sleeves or bushings a of any suitable ant1-fr1ct1on metal, fitted upon. the said bolts 5. The p1ston rods 33 are fitted slida-bly through the heads 8 of air cylinders 22,'stuliing boXes 7 being provided upon these heads 8 and housvalves 21 and 27 are arranged within the,

heads 8 and 12 respectively o f the cylinders and it will be evident particularly by re 'ence to Figure 3 that whenvthe. piston 9 moved in the direction oi? the head 12st, the respective cylinder, air will be compressed in this end of the cylinder and air will be drawn'into the other end oi? the cylinder past the valve 521. On whei'i the piston 9 is moving direction air taken into the last mentioned end of the cylinder will be, trapped and compressed, and air will be drawn into the first mentioned end of the cylinder past the The felly or the wheel above referred to comprises sections 14 and 15 which are disposed face to face and are provided at their contacting faces with a tongue and groove joint 31 which prevents relative radial displacement of the said sections. The tire for the telly is indicated by the numeral and may be of any of the ordinary sol-id types and the same is mounted upon a rim 19 which circiuni erentially fits the telly and is retained in place by annular rim. members 18 secured in place by bolts 16 which extend through lugs 18' on the inner edges of these members and through the sections 14: and 15 of the telly and which are provided with nuts 17 which may be tightened against said lugs to bind the parts together or which may be removed to permit of separation oi the parts. The sections 14: and 15 of the telly are provided with integral web portions indicated respectively by the numerals the other hand in the opposite i tight fit between the piston rods and the 14 and a ndthe said web portions 14 andv 15 are'preferably reinforced by an nular members 11 disposed against their inner sides, bolts32 being passed through the said portions 14- and 1 5- and the said members l1,hei-ng provided with spacing sleeves '38, which engage at their ends against the members 11 and hold the same. properly spaced. I

Theweb portion l t has a central opening through which access maybe had to the nut 2 for the purpose of removing the same priortqrelnoval of the wheel from the axle, v and-this opening is 1 covered by a cap plate 29 secured in position as for example by screws 28 and provided with a filling openg 1 hrough whichlubricant may be introd'iiced into the interior of the wheel,

The web 15" i's likewise formed centrally with .an opening which surrounds the inner end ofthe hub 3 and. issuitably spaced there,

from, andthe inner peripheral portion of the ,web 15" worksslidably between guard plates 24 andf25 viihichfai'e assembled in spaced relation upon the inner end of the hub and serve to close the opening in the,

said web'1 5 TheSep1ates24t and 25ers well as the spacing means therefor are retained in place by'the'brake drum, 23-which is fitted on to the inner end of the'hub 3 andfse cured in place byfmeans of bol'ts 26..

.F 110m the foregoing description ofthe invention it will be under-stood that as the wheel. passes over the road surtace and sus-- tains'the weight of the load, its cushioning cylinders 22 'will'be moved inwardly and outwardly, with the displacement of the telly orbody of the wheel with relation to,

the hub, andinthis movement the cylinders and their respectivepisto-ns 9 will berelatively reciprocated, I thus alternately drawing air into one endl of each cylinder and compressing it in the other end. the cushioning devices travel upwardly in the rotation of the wheel, air will be drawn into the outerends of the cylinders, andas.

Thus as.

the cylinders pass downwardly, this trapped air s'compressedand serves to cushion and sustain the load imposed-uponthewheel;

Having thus described the invention, what iscl'aimed as. new. is:

ing air inlets communicating with each of its ends, and check valv'es'in the said air inlets. I

2. In a cushioned wheel, a'hub, a felly, air

cylinders pivotally connected at their outer, ends with the telly, pistons pivotally con nected' at their inner ends with the hub and working in the said cylinders, each cylinder having an air inlet communicating with each of 1ts ends, and check valves 1n said inlets. In a cushioned wheel, a hub having 011?- their endsi'n the f fi'anges and extending vparallelto the axis ofthe hub, spoke sections comprising stems and transverse bearing said collars fitting the said wrist pins, a piston fixed upon the outer end of the stem, a second s'pokesection associated with each of the first mentioned sections and compris 5 ing a cylinder havlng a head provided with.

cumferenti'al flanges, wrist pins mountedat collars at'the innerends of the stems, the

trunnions, the cylinder receiving the said piston and being provided with another head through which. the stem of the respective spoke section is slidably fitted, afelly including circumferential side flanges, bear- Iings in the said flanges receiving the trunnions ,upon the first mentioned head of the cylinder, said flanges extending to points adjacent thehub, a cap plate secured to. that flange nearer the outer end of the hub, and" guard plates extending from, the inner end of the .hub. and, slidably receiving the adjacent flange.

In. testimony whereof I afiix my signature,
